To all whom #mag/ 7007206791:

B e it known that l, ACrmnnns W. OUDER'- Krnn, a citizen of the United States, residing 'at Mount Pleasant, in the county of Isabella andState of Michigan', have invent-V ed certain new V'and-useful l.Improvements in Shaft/Couplings, of which vthe following is a'specification.

This invention relates to new and useful improvements 'in shaft couplings andcontemplates improvements upon my U. S. Patent #1,261,278,vpatented April 2nd, 1918, whereby .the keys for vlocking the complementary members together-and against relative rotation maybe readily removed or dis-V Another objeetlroftheinvention toptovide a simple and inexpensive means and arrangementv `for preventing accidental displacement of the keys.

Other objects-of thej'invention will loe-' come apparent during the course of the following description.

Figure 2 is a longitudinal `section of the same, and Y w .l j Figure .3 is a transversesection of the invention taken on the line 3-3 ofFigure 1. Referring tothe drawings wherein for the purpose ofillustration is shown'the preferred embodimentof my invention, 1()V and 11 indicate generally two complementary members-of myimproved shaft coupling, each mimprisingy a discusliange 12 andl 13 respectively, formed respectively upon their outer :faces with bosses le which. are bored is conone key prevents disshafts and said boresfbeing provided with key ways 15 -whereby fthe complementaryl shaft sections@ Y Y The member `10v shown 1n viewwin VFigure members may-be securedto their respective longitudinally to receive 'the-V keIidsv off theV i 3 isprovided upon its 'fraceropposfitle the face y thereof 'hearing the'bossV 14 4with a diametrically extending ',groovefl. ,This groovefis undercut or. .dove-'tailed as yat 1 7,' more clearly shown in Figure 1." It-will'befseen that by the provisionfof v other grooves 23 .241,arranged fatwfright' Aangles. to rthe groove' 16; quadrantxshapedgspaces 1 8 vwill* be provided which appear as extensions of the front. or inner. facefo'f the'zmember.'

member 11 of the ccm-A Y .The complementar pling is .similarly provided lupon its inner face with a'dirametrical-ly 'extending groove. 20. and grooves 23 and 2,4 andwhich similarly define fourquadrant-shaped eitensicms on the face oftheange- `lilachbf.lfllese'extensov sionsV on.-lthejeomplimentaryfmember.11 is i arranged annular V'groove forthe'receptio'n provided. with `an.arcuate ggrooveflQflywhich member 10`, whereby. the twomembers will be centralized 'and j willjb'e prevented from relative* sliding movement` when assembled.

By referring more particularlyto Figure 'eef the drawing-it YWin be nearly eeen that, bothV of the diametricallyentending grooves 16 and 20, taper'ffro'm theirv larger ends"- at one sideof the couplingto the sinallerends opening into the opposite s ide of the cou- Y pling.
